My DD 7, DD 12, DH and myself will be at WDW Dec 20-24 and can't wait! It is going to be surprise for the girls and DH and I can barely contain ourselves! We are a little concerned about the crowds after reading some of these posts, especially since one of my co-workers went Dec 20-24 last year and said it wasn't crowded... Does anyone out there have any words of advice/reassurance for us?! THANK YOU!
